IMPROVEMENT IN LAMP-BURNERS..

tlje rlphrle netta tu in tiges tttttts ttnit mit mating wat rt tige samt Be it known that I, ANSON II. PLATT, of the city and county of Philadelphia, andl State of Pennsylvania, have invented a new and improved Kerosene-Burner; and I do hereby declare the {Oliv-Ying i0 be i full and vexact description of the same.

Since the first introduction of kerosene into use, it has been a great desideratum to invent an argandburner, (by whichl is meant a burner with a round wick, and a central and eircumferentialcurrent of air,) which could be adapted to ordinary glass founts now in use, but heretofore two very serious obstacles have prevented the accomplishment of this end.

First,l in order to secure the central current of air, a perpendicular aperture through the whole fount was necessary, and this was found to be impracticable in glass founts, and to get up metallic founts, expressly for the purpose was altogether too expensive to admit of general adoption into use.

Secondly, to regulate or raise and lower the wick in an argand-burner required a very complicated and Very expensive device, which, withthe first-mentioned obstacle, although the'argand is universally admitted to be the best of all light-producing structures, has prevented it from being adopted into general use.

The important feature in my invention is, that I have completely overcome these heretofore insurmountable obstacles tothe general use of the structure, and produced a burner, which, though strictly argand in all its practical eifects, can, nevertheless, be readily applied to any glass fount now in use, without even a changeof collars, and will cost but very little if any more than the ordinary burners now in the market.

Figure I represents the burner entire and ready for use, i

Figure II is a vertical'section, made at right angles with the base, and showing the arrangements of the internalparts, and

Figures III and IV are horizontal sections, made near the base, to show the workings of the regulators in raising and lowering the wicks.

In the drst place, make use of two cylinders, slightly tapering upward from their baises, and the smaller placed within the larger, with suihcient space between them to admit the wick, as shown in Fig. II, c e being the cut edges of the outer cylinder, andf j" those oia the inner; these cylinders extending down through the perforated plate 7c 7c and the burner-case S 8, and being firmly attached by their bases to the screw-plate 5 5, and extendingr upward to near' the top of the dciiector 7L 7z, 9 representing the open centre through which the central current of air passes to the flame.

I use two distinct wicks, of'equal and-uniform width and thickness, which, when properly inserted between the cylinders, which constitute the wick-tubes, precisely iill the space at lthe top or upper` ends, and, as the cylinders ilare downward, there must necessarily he a triangular space upon opposite sides of the cylinders, whielipis not iilled bythe wicks, the base of this triangular space being down, and the apex at the upper end ofthe cylinders.

I next cut out this triangular space in the cylinders, between the wicks, from the base upward, from 'onehalt` to three-fourths of its length, as seen at b b, Fig. II, and close up the cut edges to prevent leakage from the wicks, and secure the structure from combustion and explosion, and these triangular spaces, thus out out upon opposite sides of the two cylinders, aii'ord a free admission of air from without to form the central current of air within, Fig. II, 9, which is indispensable to an argand.

In the struct-ure of very large argand-burners, where a greater central current of air might be needed,- han could be secured through the triangular spaces l) b, Fig. II, I make two separate semicircuiar wick-tubes,

Fig. IV, 3 3, of equal and uniform width, and insert one end ofwthem in the screw-plate, 5 5, of the burner-case 8 8, Fig. II, with their bases set apart, Fig. IV, 3 3, sufficiently to admit the necessary quantity of air, and

place the upper end or edges in contact, so as to form a cylindrical fiume, and still leave the whole triangular space, from base to top, open for the admission of air, and clit through the inner plete of the tubes to allow the wheel to come in contact with the wick, as seen, Fig. II, c c c e.

In order to regulate the wicks when cylinders are used, as shown in Fig. II, I pass a shaft, Fig. III, 4 4, through the triangular open space b Zz, Fig. II, and give the end 6, Fig. III, a stationary attachment, while the other end, 4 4, has a lateral motion in a horizontal slot, and a milled head as the means oi' moving it.

To this shaft, in the centre ofthe inner cylinder, is attached, transversely to it, and perpendicularly to the i cylinder, a notch-wheel, Fig. II, 4, and opposite the notched edges ot' this'wheel there is a slot or hole, c c c c', Fig. II, cut through the inner cylinder, so that by pressing thc wheel to either side and turning'igit will come' in contact with the wick, and move it up or down at pleasure.

When the semicircular tubes are used instead of cylinders, I cut through the inner platepf each tube and apply the wheel as n the case of the cylinders, as seen in IV.

In "ery large argands, where onewheel might not be adequate to move so broad ncircular wick, I sometimes apply two double-ratchet regulators upon the outer ond opposite sides of the cylinders or semicircular tubes, cutting through the outer plates ofthe latter, so as to allow the ratchets to come in contact with the outer surface of the wicks, and then work the regulators, as in the usual way, by a simple rotary motion.

a a, Fig. II, is the apron, which is attached to the top ofthe burner-case, 8 8, and extends down nearly to thefount on which the burner stands, and aids much in giving;r steadincss and portability to the flame'. Adtmimges. v

First, this burner never hea-ts, even to palpable warmth, and generates no gases, and consequently cannot explode. v

Secondly, it produces the most brilliant light of any other light-producing structure in existence, and about one-eighth more light from a given quantity of oil than any other now known.

Thirdly, the'ame and chimney both being round', all parts ofthe latter heat so nearly simultaneously that it is impossible to break achimneywith the flame or heat.

And, lastly, all concur in the opinion that this is the most compact, neat, and dcomely burner which has ever been produced.

What Iclaim as my invention, and desire to securcby Letters Patent, is-

The'coinbination and arrangement of the concentric wick-tubes or plates 2 3, with open spaces b 6 therein, the movable wick-regulator 4,' perforated plate 7c, and apron a, substantially as'and for thepurposes herein specified. I
